Latest Patents

Yu-Che Tsai holds a patent for a "Lightweight orthogonal frequency division multiple access (OFDMA) scheduler for low latency applications." This OFDMA scheduling device is designed to receive a data stream from a network router and can identify audio packets based on metadata. The device is capable of recognizing the number of wireless devices connected to it and determining a resource unit (RU) allocation for each device based on their payload. Additionally, it can ascertain a modulation and coding scheme (MCS) for each device based on the received signal strength indicator (RSSI) value and any feedback data from the devices. Ultimately, the OFDMA scheduling device sends a downlink OFDMA frame to the wireless devices, informing them of their respective RU allocations and the MCS to be used for receiving audio packets.
